TIP-FOR CORDS.

SIECIFIGATION forming part of Letters Patent No. 734,500, dated July 28, 1903.

Application filedllanuary 17, 1899- Serial No. 702,483. (Nomodeld To all whom it may concern.-

Be it known that I, JOHN R. BARRETT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tips for Cords, of which the following is a specification, reference being. had to the accompanying drawings.

My invention relates to tips for-cords, and has for its object to provide an improved cordtip having a solid or substantially solid point and a tubular portion to receive and retain the end of the cord. This object I accomplish as hereinafter described and as illustrated in the drawings.

What I regard as new will be set forth in the claims.

In the accompanying drawings, Figure l is a view of the blank from which the tip is formed. Fig. 2 is a View showing the blank partially wound upon the cord. Fig. 3 is an elevation of thecompleted tip with the cord in place. Fig. 4 is a longitudinal section of the same, and Fig. '5 is a cross-section on the line 5 5 of Fig. 4.

Referring to the drawings, A indicates the blank from which the tip is formed, said blank being of the shape illustrated in Fig. 1 and consisting of a substantially rectangular section a at the rear and a tapered section b at the front, the rear portion of said tapered section being somewhat wider than the section a,forming a laterally-projecting wing c, as shown. The rear margin of the section a is rounded slightly, so that when rolled up no projecting corners will be formed. The edge of the section a adjacent to the wing c is serrated, as shown at d in Fig. 1.

In forming the tip from the blank A the wing c is first rolled up solidlyi. e., in spiral form-until it reaches the edged. The

end of the cord having been placed in position on the section a, the rolling of the blank is then continued, the edge cl entering and firmly engaging the end of the cord which is is formed.

That which I claim as my invention, and desire to secure by Letters Patent, is-

1. A sheet-metal tip for cords, consisting of a spirally-rolled pointed end formed of sheet metal and a projectingattaching portion, substantially as described.

2. A sheet-metal tip for cord s,.consisting of a spirally-rolled pointed end and a tubular rear portion adapted to receive the cord, substantially as described. i

3. A sheet-metal tip for cords, consisting of a substantially solid pointed end and atubu'lar rear portion adapted to receive the cord, said tip being formed from a rolled blank, substantially as described.

4c. A tip for cords, having a substantially solid pointed end, and a tubular rear portion adapted to receive the cord, said tubular portion having a serrated edge which engages the cord, substantially as described.

5. A tip-blank, consisting of a substantially rectangular rear section a and a tapered front section b, the latter section having a wing c, the whole being of thin metal capable of being rolled up to form a tip, substantially as described. 7

6. A sheet-metal tip-blank, consisting of a substantially rectangular rear section a having a rounded rear end and a tapered" front section b, the latter section having a wing'c, substantially as described.
